Architecture, archaeology and continuing use
The monument is identified as a fort through its enclosed earthwork defences. Exact dimensions and internal features are not supplied by the accessible designation text, so interpretation should focus on the protected enclosure and its landscape position.
Its story
The fort belongs broadly to Scotland’s prehistoric defended-settlement tradition. It was among the monuments scheduled in 1927, and its legal protection was amended in 1961. Later recording has retained the established identity without providing a modern excavation-led chronology.
Why it is included
National protection reflects the fort’s survival and potential to preserve evidence for settlement, defence and land use even where a fuller modern description remains unavailable.
What to notice
- Concentric or ring-like lines of defence.
- The relationship between enclosure and surrounding slopes.
- Subtle interior ground that may conceal structures.
Reading the surroundings
Seek landowner permission or use only confirmed public routes. Keep away from crops and livestock, do not move stones and never excavate or metal-detect.
